| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | PALB2 K346Tfs*13 indicates a shift in the reading frame starting at amino acid 346 and terminating 13 residues downstream causing a premature truncation of the 1186 amino acid Palb2 protein (UniProt.org). K346Tfs*13 has not been characterized, however, due to the effects of other truncation mutations downstream of K346 (PMID: 31757951, PMID: 31636395), is predicted to lead to a loss of Palb2 protein function. |
